Every ISIS&GOLD gold jewel is cast, polished and checked in our Nice workshop. Nothing is bought ready-made.
We start from 750 thousandths gold: 75% pure gold, alloyed with silver and copper. It is the reference standard of French fine jewelry.
Each piece is cast one by one in our Nice workshop, from our own models.
The mirror finish is done by hand. It is what gives the jewel its light once it sits on the enamel.
Weight, dimensions, surface condition: every jewel is inspected before being packed with its certification card.
Gold does not oxidise
Gold does not oxidise. That is chemistry, not marketing: pure gold reacts neither with air, nor water, nor saliva. A jewel in 18K solid gold cannot rust, and cannot tarnish from within. Whenever the look changes, the cause is on the surface — and it can be undone.
« My jewel looks dull, as if veiled »
A deposit has settled on the surface: dental plaque, tartar, toothpaste residue. The gold underneath is untouched — it is the deposited layer that no longer reflects the light.
A scaling, or a gentle clean at your technician's, is enough to bring the shine back.
« My jewel has darkened »
Gold itself does not darken. What takes on colour is what clings to the surface — coffee, tea, red wine, tobacco — or, more rarely, the 25% of alloy (silver, copper) in contact with sulphur or chlorine: swimming pools, whitening products, some mouthwashes.
It stays on the surface. Re-polishing gives the jewel back its original look.
« It is the rim around the jewel that has yellowed »
That is not the jewel: it is the composite holding it. This dental resin is porous and absorbs pigments over time, exactly like a filling does. By far the most frequent case.
The composite is renewable. Your technician removes it and re-bonds the jewel — the gold itself is reused as it is.
« The shade looks different to me »
The shade of 750‰ gold comes from its proportion of silver and copper, and it is always read against the tooth next to it. Teeth whitening, a different light, another phone camera: the jewel has not changed, its surroundings have.
Compare in daylight, on the same tooth. If a doubt remains, write to us.
Gold is the oldest metal in dentistry, and that is no accident.
Inlays, crowns, bridges: gold has been used in the mouth since the late 19th century, precisely because it does not corrode in contact with saliva.
The 750‰ alloy combines gold, silver and copper. It contains no nickel, the metal most often behind contact allergies. Allergy to gold itself is exceptional.
The jewel is bonded onto the enamel, like a tooth gem. No preparation of the tooth, no drilling. Removal must be done by a health professional.
750 duizendsten, oftewel 75 % zuiver goud in de legering: dat is de definitie van 18-karaats goud. De overige 25 % (zilver, koper) geven het sieraad zijn kleur en duurzaamheid.
Elk gouden sieraad wordt geleverd met zijn certificeringskaart: aankoopdatum, referentie, bestelnummer en tandsieraadspecialist(e). De QR-code op de kaart leidt naar deze pagina.

Goud van 750‰ verkleurt niet. Lauw water en een zachte borstel volstaan. Het verwijderen van een tandsieraad moet door een zorgverlener gebeuren.
Yes, by a health professional or by your tooth gem technician. The enamel is neither prepared nor drilled: the fitting is reversible.
Harten, letters, sterrenbeelden, maatwerk: de hele collectie wordt in Nice van massief goud gemaakt.
